The lens boards for Super are more "complex" than for example a Crown. One can find the nonSuper boards w/o much effort. It seems like finding a Super board (with the shutter trip etc) is very difficult. Any hints to finding one?

Also a Schneider 110 Super Symar XL might fit in a Super and close lid. The lens diameter is narrow enough to fit between the rails just to clear the tracks, but hits the narrowest part of the rail.
